Bars are how producers and engineers talk; minutes are how platforms and listeners do. This converts between them for any tempo. The table underneath blocks out a whole song at that tempo, so you can see where the hook lands before you write it.

The maths, if you want it
One beat lasts 60 ÷ BPM seconds. In 4/4, one bar is four beats, so a bar lasts 240 ÷ BPM seconds. At 140 BPM that is 1.71 seconds per bar; 16 bars is 27.4 seconds; 64 bars is 1:50. Half-time drums do not change the count: the bar is still the bar, the drums just hit half as often.
Why it matters
- Streaming counts a play at 30 seconds. An 8-bar hook at the top reaches the listener inside that window at any tempo above 64 BPM.
- A “three-minute song” at 150 BPM is about 112 bars; at 90 BPM it is 67. Same length, very different amount of writing.
- Engineers quote edits in bars. Knowing “cut 8 bars” is “cut 13 seconds” at your tempo makes the conversation quick.
